Copyright 2007-2022 UAB Softneta1 IntroductionMedPream PACS is a DICOM 3.0 compliant PACS (Picture Archive and Communication System) application thatcombines the following components in one machine or one box: A DICOM server. A PACS server which uses open source MySQL database. A Web server which uses open source Apache 2.0 HTTP server and PHP (recursive acronym for "PHP:Hypertext Preprocessor") scripts. A optional HL7 interface to receive and send HL7 messages via Lower Level Transport Protocol (LLTP)The benefits of MedPream PACS over the traditional PACS servers are: It is low cost (Premium Edition) since it uses open source MySQL database and Apache web servers. It makes the life of a PACS administrator a lot easier since there is only ONE instead of multiple servers orboxes to maintain. Users can freely choose their favorite server platform or hardware, whether it is a PC, workstation, fullyfledged server with RAID disk arrays or even a laptop, to install and run MedPream PACS server software. Users can freely choose their favorite operating system software, whether it is Linux, Mac OS X, Windows2008/2012 Server or Vista/Windows 7/Windows 8/Windows 10. Archiving of the PACS database is just as simple as backing up files on a regular server, which makesMedPream PACS fit seamlessly into the rest of IT infrastructure of the entire organization. A PACSadministrator has the freedom to choose their favorite backup solutions, software and/or archive media.This implementation of MedPream PACS server is designed to provide the following features: The application serves as a short-term archive for images. It accepts images from external sources andstores them for later retrieval. MedPream PACS uses DICOM as the interface to external conforming clients. The DICOM server acceptsDICOM association requests for the purpose of storing images and for image query and retrieve.MedPream PACS server will initiate DICOM association requests for the purpose of sending images to anexternal server, querying remote application entities, or printing images to remote Dicom printers.MedPream PACS server does not respond to any other type of network communication. MedPream PACS uses Apache Web server as the interface for viewing and managing the PACS database,and for reviewing images on-line through a web browser. The Premium Edition of MedPream PACS Server supports Automatic Image Routing Table, where userscan define routing entries based on the following criteria:MedDream PACS Premium 7.2.6Page 5
Copyright 2007-2022 UAB SoftnetaFieldSourceApplicationEntity (AE)TitleKey AttributeTagDescriptionImages received from the matching Source AE Title will be routed to the destination AEautomatically based on the specified Schedule below.Currently, the Patient ID (0010,0020), Referring Physician's Name (0008,0090)and Protocol Name (0018,1030) key tags are supported. Users can define a matching patternstring with wild-card characters including '*' and '?', so that if the received image attributematches with the specified pattern string, MedPream PACS Server Premium Edition willautomatically route the received image to the destination AE based on thespecified Schedule below.Destination AEThis is the destination AE where the received images will be routed.TitleRoute Immediately (as soon as received), a [From, To] window, or based on a fixed 24Schedulehour clock.Whether or not to purge received images after they have been routed successfully to theAuto Purgedestination AE(s). The Premium Edition of MedPream PACS Server supports querying remote DICOM Modality Worklist(DMWL) SCP applications and displaying the query results through the web user interface. The Premium Edition of MedPream PACS Server supports receiving event notifications sent by remoteDetached Study Management SCP applications, as well as querying remote Detached Study ManagementSCP applications for study related information. The Premium Edition of MedPream PACS Server supports storage of DICOM V3.0 Strucutre Reports(SR), as well as presentation of the Structure Reports through the web user interface. The Premium Edition of MedPream PACS Server supports DICOM Media Storage Services and FileFormat (PS 3.10) as a File Set Creator (FSC) and File Set Reader (FSR) of the General Purpose CD-Rand DVD Interchange Profiles. From the MedPream PACS web user interface, users can export selectedpatients/studies in the MedPream PACS database to a local directory using DICOM standard directoryformats (DICOMDIR), which can later be archived into CD-R/RW or DVD-R/RW/RAM for mediainterchange. Uses can also import external patients/studies from a DICOM Media Storage Servicecompliant directory or CD/DVD media into the MedPream PACS database. The Premium Edition of MedPream PACS Server Supports the Automatic Purging StorageDirectories feature by allowing the user to define a set of Low-Water and High-Water Marks in terms ofdisk usage percentage for MedPream PACS Server archive directories. If Enabled by the user and the diskusage percentage of the archive directories has dropped below the user-defined Low-Water Mark,MedPream PACS Server Premium Edition will start to purge older studies stored in the archive directories,by the order of the date the studies were received, until the disk usage percentage has risen above the userdefined High-Water Mark. User can also specify optionally a Destination Folder to move aged studiesinstead of permanently delete the aged studies. The Premium Edition of MedPream PACS Server supports printing both color and grayscale images toDicom compliant remote printers from the MedPream PACS Server web user interface. The Premium Edition of MedPream PACS Server supports synchronizing its local database with remotestudies stored on external application entities based on user-specified schedule (s). Users can also selectwhether to synchronize all remote studies or only those recent studies received in the past N days.MedDream PACS Premium 7.2.6Page 6
Copyright 2007-2022 UAB Softneta2 Implementation ModelMedPream PACS Server provides for storage, query/retrieval and management of Dicom formatted images andreports. It runs on the following platforms: Windows 2008/2012 Server Windows Vista/Windows 7/Windows 8/Windows 10 Linux (Premium Edition) Mac OS X (Premium Edition)as a background process (service) that accepts association requests from external applications. MedPream PACSserver employs a configurable thread pool to service requesting applications. MedPream PACS server will initiate aDICOM C-STORE association in response to either a C-MOVE request from an external application, userforwarding requests entered from the web user interface, or matches with automatic image routing table entries.MedPream PACS server is started automatically when Windows starts up, users which have WindowsAdministrator's privilege can stop and re-start MedPream PACS server process manually from the "Services" tabletof the Windows Control Panel.The following parameters of the MedPream PACS server are configurable by executing the 'SETUP.EXE' programduring Installation, or by modifying the Windows Registry values manually under the following key for Windowsplatforms:HKEY LOCAL MACHINE\\SOFTWARE\\RainbowFish Software\\MedPream PACS\\ {AeTitle}\\or by modifying the " {AeTitle}.ini" configuration file under the directory where MedPream PACS Server isinstalled for Linux/MacOS platformsRegistry ityTitleApplication Entity (AE) title of MedPreamPACS ServerStringMyAeTitleServerPortNumberTCP port number MedPream PACS Serverlistens toDWORD 1234LogDirectoryDirectory path where MedPream PACS Serversaves the log filesString'log' sub-directory whereMedPream PACS Server isinstalledDatabaseName of MySQL database created forMedPream PACS ServerStringSame as AE title ofMedPream PACS ServerStorageFormatStorage format for received images.

As noted above, MedPreamPACS server does not initiate any action except in response to requests which are received either via DICOMassociations or from the web user interface.Figure 1 MedPream PACS Server Implementation Model2.2Functional Definition of Application EntitiesMedPream PACS server waits for another application to connect to the TCP/IP port number specified when theapplication is initiated. When a DICOM association request is received, MedPream PACS server uses a MySQLdatabase table and the following logic to verify the incoming request:MedDream PACS Premium 7.2.6Page 8
Copyright 2007-2022 UAB Softneta2.3 MedPream PACS server is permissive when verifying the Called Application Entity Title of the incomingassociation request. It does not reject an incoming association request based on the specified CalledApplication Entity Title. PaceOne server queries the 'applentity' table to verify if there is a row whose 'title' field matches (caseinsensitive) with the Calling Application Entity Title of the incoming request. If there is a match, MedPream PACS server then verifies that the matching application entity has access tothe MySQL database, by querying the 'allowaccess' field of the 'applentity' table. If 'allowaccess' field is Enabled (non-zero), MedPream PACS server then proceeds to service the incomingassociation request. If 'allowaccess' field is Disabled ('0') or no matching application entity is found for the Calling ApplicationEntity Title, MedPream PACS server will reject the incoming association request from this applicationentity.Sequencing of Real-World ActivitiesSee the Association Initiation and Acceptance Policy sections below on real-world activities for all SOP classessupported by MedPream PACS Server.MedDream PACS Premium 7.2.6Page 9
Copyright 2007-2022 UAB Softneta3 AE SpecificationsMedPream PACS server is started automatically when Windows starts up, or user can manually stop and re-startMedPream PACS server from the 'Services' tablet of the Windows Control Panel. MedPream PACS server uses aconfigurable thread pool to service all DICOM 3.0 protocol I/O processing. The number of threads in the threadpool has a default value of 2, and can be configured by modifying the following Registry value for Windowsplatforms:HKEY LOCAL MACHINE\\SOFTWARE\\RainbowFish Software\\MedPream PACS\\ {AeTitle}\\ThreadPoolSizeOr by modifying the following variable in the " {AeTitle}.ini" configuration file under the directory whereMedPream PACS Server is installed for Linux/MacOS platforms:ThreadPoolSize 2NOTE: Setting a large value for the number of threads in the thread pool does not necessarily increase the overallperformance of MedPream PACS server. It is recommended to set the size of thread pool to be twice the number ofavailable processors or CPU's in the system. MedPream PACS server needs to be re-started if the size of thread poolis modified.3.1AE MedPream PACS Server - SpecificationMedPream PACS server provides Standard Conformance to the following DICOM 3.0 SOP Classes as a SCU:SOP Class NameSOP Class UIDVerification SOP Class1.2.840.10008.1.1Computed Radiography Image Storage1.2.840.10008.5.1.4.1.1.1Digital X-ray Image Storage - For Presentation1.2.840.10008.5.1.4.1.1.1.1Digital X-ray Image Storage - For Processing1.2.840.10008.5.1.4.1.1.1.1.1Digital Mammography X-ray Image Storage - For Presentation1.2.840.10008.5.1.4.1.1.1.2Digital Mammography X-ray Image Storage - For Processing1.2.840.10008.5.1.4.1.1.1.2.1CT Image Storage1.2.840.10008.5.1.4.1.1.2Ultrasound Multi-frame Image Storage (retired)1.2.840.10008.5.1.4.1.1.3Ultrasound Multi-frame Image Storage1.2.840.10008.5.1.4.1.1.3.1MR Image Storage1.2.840.10008.5.1.4.1.1.4Nuclear Medicine Image Storage (retired)1.2.840.10008.5.1.4.1.1.5Ultrasound Image Storage (retired)1.2.840.10008.5.1.4.1.1.6Ultrasound Image Storage1.2.840.10008.5.1.4.1.1.6.1Secondary Capture Image Storage1.2.840.10008.5.1.4.1.1.7Standalone Overlay Image Storage1.2.840.10008.5.1.4.1.1.8Standalone Curve Storage1.2.840.10008.5.1.4.1.1.9Standalone Modality LUT Storage1.2.840.10008.5.1.4.1.1.10Standalone VOI LUT Storage1.2.840.10008.5.1.4.1.1.11X-Ray Angiographic Image Storage1.2.840.10008.5.1.4.1.1.12.1X-Ray Radiofluoroscopic Image Storage1.2.840.10008.5.1.4.1.1.12.2X-Ray Angiographic Bi-plane Image Storage (retired)1.2.840.10008.5.1.4.1.1.12.3MedDream PACS Premium 7.2.6Page 10
